DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
There has for a long time been a need for a portable dance floor, which can be assembled and positioned wherever and whenever needed, and later can be readily disassembled and stored for later use. Hardwood flooring, preferred for dancing, is easily marred by those walking on it, and so it is not used as a permanent flooring where there is much foot traffic and only occasional dancing. In hotels and recreation centers, rooms for banquets or conferences are frequently carpeted from wall to wall to provide comfortable walking and to reduce noise. Dancing is not possible on carpets and accordingly a quick setup/break down dance floor is needed to accommodate dancing. Prior to now the available portable dance floors have had many flaws, principally relating to the means for joining sections so as to produce a level dancing surface, free of irregularities in height and spacing of adjoining sections. Other problems develop when Allen head screws used to join adjacent dance floor sections become too worn for the wrenches to work well and when threads become stripped.
It is an object of this invention to provide a novel portable dance floor. It is another object to provide a portable dance floor that has improved joining means between sections so as to produce a level top surface and perfect joining surfaces. Still other objects will become apparent from the more detailed description which follows.
BRIEF SUMMARY OF THE INVENTION
This invention relates to a portable dance floor comprising a plurality of assemblable identical square sections and a plurality of ramp members attachable to said sections to form a sloping perimeter around the dance floor, each said square section having a top horizontal surface, a bottom horizontal surface, and four vertical side surfaces including a generally square central core sheet of weight supporting material with a dance floor material covering its top surface, a structural beam portion around its perimeter to which are attached cooperating magnetic attraction means adapted to detachably join said square sections to each other and to detachably join said ramp members to said square sections.
In specific and preferred embodiments of this invention the dance floor sections have a light weight plastic honeycomb material as a core, a top surface of hardwood flooring and sides of wood, aluminum, or plastic beams to which are affixed magnets, wedge-shaped tongues, and recesses to provide a tight, accurately positioned coupling between adjoining sections .
BRIEF DESCRIPTION OF THE DRAWINGS
The novel features believed to be characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings in which:
FIG. 1 is a top plan view of the dance floor of this invention including four joined dance floor sections and ramps around the perimeter;
FIG. 2 is a side elevational view of the dance floor of FIG. 1;
FIG. 3 is a top plan view of one dance floor section;
FIG. 4 is a side elevational view of the one section shown in FIG. 3;
FIG. 5 is a front elevational view of the section shown in FIGS. 3-4;
FIG. 6 is a cross sectional view taken at 6--6 of FIG. 3 using metal structural beams;
FIG. 7 is a cross sectional view taken at 7--7 of FIG. 3 using metal structural beams;
FIG. 8 is a cross sectional view taken at 8--8 of FIG. 3 using metal structural beams;
FIG. 9 is a cross sectional view taken at 9--9 of FIG. 3 using metal structural beams;
FIG. 10 is a cross sectional view taken at 10--10 of FIG. 3 using metal structural beams;
FIG. 11 is a cross sectional view taken at 6--6 of FIG. 3 using wooden structural beams;
FIG. 12 is a cross sectional view taken at 8--8 of FIG. 3 using wooden structural beams;
FIG. 13 is a cross sectional view taken at area 37 of FIG. 1 looking vertically downward be
